The authors have developed the mechanism which gives vibration to electrical contacts by hammering oscillation and studied the influences of a micro-oscillating on the contacts. In time field, by means of combinations of unit step functions as external force, using approximation of material particle, they carried out mathematical approach and the simulation of dynamical characteristics of the mechanism with a personal computer (PC). In addition, in space field, it was suggested that the analytical modelings of thin film and thin board were carried out using continuous approximation. By making use of this model and by experimental estimation of initial & boundary conditions, it was possible for estimation approximately of fundamental mechanical quantities, such as displacement, acceleration and mechanical energy. |
